The present disclosure relates to the field of image analysis, inparticular, it relates to a method for augmenting a first image usingimage data from a second image. The disclosure also relates to a devicecomprising circuitry configured to carry out the method. The disclosurealso relates to a computer program product adapted to carry out themethod.

BACKGROUND

In image search approaches, it is often desirous to determine andidentify which objects are present in an image. Image search approachesand image recognition approaches are common for commercial use, forexample to generate product catalogues and product suggestions. It hasbeen desirous to achieve a system where a user can take a photograph ofa room, where the image search process can use image data to searchproduct catalogues on the internet to return for example differentstores' prices for a given product.

It is often desirous to augment an image such that it can easily bemanipulated by a user. This is beneficial for industrial areas wherepredicting visualizations are can be used such as building constructionor indoor design.

Typically, an image can be augmented such that a data model of an objectcan be placed in the image such that a user can visualize how the scenemay look like with the added model. However, these methods are limited,and the final augmented image is a virtual image wherein the realness ofthe object is missing, since it is constructed from a model.

Therefore, there is room for improvements in the field of image analysisand augmenting of images.

SUMMARY

In view of that stated above, an object of the present disclosure is toprovide a method for augmenting an image with image data relating to anobject such that the augmented image contains real image data for theobject. It is further an object to use image analysis and imagemanipulation approaches to achieve the above in an automatic orsemi-automatic fashion.

To achieve at least one of the above objects and also other objects thatwill be evident from the following description, a computer implementedmethod, a device for carrying out the method, and a computer programproduct for carrying out the method provided according to the presentdisclosure. Preferred embodiments of the device will be evident from thedescription.

According to a first aspect, there is provided a computer implementedmethod for augmenting a first image with image data from a second image,the method comprising:

receiving the first image depicting a first scene;

capturing the second image depicting a second scene using an imagecapturing device;

identifying an object in the second image;

receiving a 3D model from a database, the database comprising aplurality of 3D models, the 3D model corresponding to the identifiedobject of the second image;

aligning the 3D model with the identified object in the second image;

extracting pixel data from the second image using a contour of the 3Dmodel's projection onto the second image;

inserting the extracted pixel data of the second image data into thefirst image, thereby rendering an augmented image.

Objects in the second image may be segmented (extracted, distinguished,etc.,) using any known algorithm, such as algorithms using one or moreof edge features, binary patterns, directional patterns, Gradientfeatures, Spatio-Temporal domain features etc.

The step of identifying an object in the second image may be done by animage search algorithm. By the term “image search algorithm”, should inthe context of the present specification, be understood as any known wayto search for images (of objects) in a database which are similar to anobject of the image and use the outcome (e.g. labels/classification ofsimilar images found in the database) to classify the object. Examplesof known commercial image search algorithms at the filing of thisdisclosure comprises Google images, TinEye and Alibabas Pailitao.

The provided method is an improved method for augmenting an image andkeeping the augmented image realistic. By adding image data from thesecond image, the realistic view of the augmented image may be achieved.

By receiving a 3D model for the identified object, the imagesegmentation may be improved such that only, or almost only, the imagedata pertaining to the identified object is extracted, and such that allor almost all image data pertaining to the identified object isextracted. The received 3D model is thus used to decide which part ofthe second image to extract image data to avoid extracting anysurrounding of the object. This may improve the augmented image byimproving the realistic view of the image in an efficient manner. Alow-complexity process for adding image data from a second image to afirst image may thus be achieved.

The provided method allows a user to augment an existing image withimage data from another image (e.g. newly taken) to see what an objectmay look like in the scene of the first image.

According to some embodiments, the method further comprises

determining a first 3D coordinate space of the first image;

determining a second 3D coordinate space of the second image;

determining an object coordinate for the identified object in the secondimage using the second 3D coordinate space, and

wherein inserting the extracted pixel data of the second image data intothe first image comprises inserting the extracted pixel data, at aposition coordinate in the first image corresponding to the objectcoordinate. By determining a first and second 3D coordinate space, alow-complexity model for inserting pixel-data into the first image maybe achieved. With the position coordinate corresponding to the objectcoordinate the predictability for where in the first image the pixeldata is inserted may be more precise.

Thereby, placement of the extracted pixel data at a desirous position inthe first image is facilitated. Accordingly, the desired position may beeasy to manipulate due to the adapted 3D coordinate spaces between thetwo images.

By way of example, if the identified object in the second scene is achair at a right bottom corner of the second scene, the extracted pixeldata of said chair may be automatically placed at a bottom corner of thefirst scene.

According to some embodiments, the method further comprises adjustingthe position of the extracted pixel data in the augmented image by:

zooming in or out, or translating the first image, thereby manipulatingthe first 3D coordinate space of the first image,

adjusting the position of the extracted pixel data in the augmentedimage to correspond to the object coordinate in the manipulated 3Dcoordinate space of the first image.

By adjusting the position of the pixel data in the augmented image,image manipulation of the augmented image may be facilitated in anefficient manner. The manipulation of the first image allows formanipulation of the augmented image without requiring manipulation ofthe extracted pixel data, or without requiring that a new image of theobject is captured, thus leading to a simplified procedure foraugmenting the first image with image data from the second image.

According to some embodiments, the method further comprises

for the 3D model, defining a first value for a scale parameter, a firstvalue for a translation parameter, and a first value for a rotationparameter,

for the identified object in the second image, defining a second valuefor a scale parameter, a second value for a translation parameter, and asecond value for a rotation parameter, and

aligning the 3D model to the determined 3D coordinate space of thesecond image by manipulating one or more of the first scale parameter,the first translation parameter and the first rotational parameter ofthe 3D model, such that the first scale parameter corresponds to thesecond scale parameter, and the first translation parameter correspondsto the second translation parameter, and the first rotation parametercorresponds to the second rotation parameter. The alignment of the 3Dmodel to the identified object in the second image may be performed inan efficient and automatic manner by the rotation, movement or scalingof the 3D model. An image algorithm may be applied to the image and the3D model to determine when the 3D model has a proper alignment with theidentified object.

According to some embodiments the method comprises

requesting an input from a user;

receiving an input from the user, and wherein the step of receiving the3D model comprises sending data pertaining to the received input to theidentified object to the database. By utilizing a user input, theprocessing power needed to perform the step of receiving a 3D model maybe reduced. The user input may pertain to the identified object in thesecond image, and accordingly, data may be sent to the databaserequesting a 3D model of such identified object. The user input may insome embodiments pertain to a category or object type of the identifiedobject, accordingly lessen the processing time needed to receive a 3Dmodel corresponding to the identified object.

A user input may allow the method to omit processing steps, leading to amore efficient method for augmenting a first image with image data forma second image. The user input may be requested and received in anyknown manner such as using a graphical user interface, a voiceinterface, etc.

According to some embodiments, the method further comprises.

identifying one or more objects in the first image; and

removing at least one of the one or more identified objects in the firstimage or manipulating at least one of the one or more identified objectsby changing a position of at least one of the one or more identifiedobjects in the first image.

By removing, or changing a position of, an object, an empty space in thescene may be created. Consequently, the present embodiment allows forrearranging the scene in the first image as desired to fit the pixeldata of the identified object from the second image. Any known method orsoftware for changing a position of, or removing, an object in an imagemay be employed.

According to some embodiments, the method further comprises

removing the inserted pixel data from the augmented image;

capturing a third image of the second scene using the image capturingdevice;

re-identifying the previously identified object of the second image inthe third image;

calculating a third 3D coordinate space for the third image;

aligning the 3D model with the identified object in third image;

extracting pixel data from the third image of a contour of the 3D modelprojection onto the third image;

determining a second object coordinate for the identified object in thethird image using the third 3D coordinate space;

inserting the extracted pixel data of the third image data into thefirst image at a position coordinate in the first image corresponding tothe second object coordinate.

As such, the augmented image may be manipulated in a simple manner,where the first image is left untouched, and the second image isre-captured as the third image to provide a low-complexity method. Byway of example, if a user is unsatisfied with the positioning of theidentified object in the augmented image, the user may capture a newimage of the second scene comprising the identified object. By the userand the capturing camera device changing position or angle in relationto the identified object, the second object coordinate is manipulatedand accordingly, the position coordinate may be manipulated.Advantageously, a low-complexity method may be provided where therealistic view of an augmented image may be manipulated in a simplemanner.

According to some embodiments, the step of identifying the object in thesecond image comprises determining an object type using an image searchalgorithm. Any suitable image search algorithm may be used to determinethe object type. By determining the object type for the object, themethod may identify the object in a more efficient manner. Bydetermining the object type, the receiving of the 3D model may be basedon the object type. For example, if the object type is deemed to beutensils, the received 3D model may be of the same object type, thussaving time during calculations.

According to some embodiments, the step of identifying the object in thesecond image comprises scanning a QR code on the object to be identifiedin the second scene. The QR code may comprise data pertaining to theobject type of the identified object. It is to be noted that the QR codemay contain a variety of relevant data for identifying the object. Thedata contained in the QR code may be sent to the database for thereceiving of the 3D model. The QR code may in some embodiments comprisedata pertaining to a 3D model of the object having said QR code, e.g. anidentifier for the 3D model in the database.

According to some embodiments, the step of identifying the object in thesecond image comprises reading a beacon signal transmitted by the objectto be identified in the second scene. By way of example, the beaconsignal may determine which object in the image is closest to the cameradevice, and thereby said object may be the chosen object to beidentified. The beacon signal may comprise data identifying the objectand such data may thus be transmitted to the database to receive thecorresponding 3D model from the database.

According to some embodiments, the step of receiving the 3D modelcomprises sending image data pertaining to the identified object to thedatabase. As such, mapping the image data to a corresponding 3D modelmay be performed by e.g. a server hosting the database. Consequently,the computational power required to perform the method of augmenting thefirst image with image data from the second image may be advantageouslydistributed between several devices . . . .

According to some embodiments, the step of capturing a second imagecomprises using AR or VR equipment, and wherein the method furthercomprises displaying the augmented image using said AR or VR equipment.By using AR or VR equipment the augmented image may be realisticallydisplayed to a user.

It is to be noted that the second image may be captured using any cameradevice.

According to some embodiments, the method further comprises storing theaugmented image in a memory. It is to be noted that the memory may alsostore the first image. The memory may also store the second image. Datapertaining to the executed steps of the method may be stored in thememory. By storing the augmented image in the memory, the method may beperformed iteratively such as to become more and more automatic andquicker in terms of processing. In other words, by the memory storingdata pertaining to the images and optionally method steps performedthereto, the memory may generate a compilation of examples of how to forexample place an object in the first image. The memory may gather datapertaining to common placements of object types in relation to aspecific scene. Such data may be utilised by the memory to recommendmanipulations of any one of the images or to recommend a position forplacement of the extracted pixel data.

According to a second aspect, there is provided a device configured toaugment a first image with image data from a second image, the devicecomprising circuitry configured to perform the method of the firstaspect.

According to a third aspect, there is provided a computer programproduct comprising a computer-readable storage medium with instructionsadapted to carry out the method of the first aspect when executed by adevice having processing capabilities.

DESCRIPTION OF EMBODIMENTS

The present disclosure will now be described more fully hereinafter withreference to the accompanying drawings, in which currently preferredembodiments of the disclosure are shown. This technology describedherein may, however, be embodied in many different forms and should notbe construed as limited to the embodiments set forth herein; rather,these embodiments are provided for thoroughness and completeness, andfully convey the scope of the invention to the skilled person.

In the following, a method will be described for augmenting a firstimage with image data form a second image. The method may facilitateaugmentation of images and by doing so improving the realistic view ofan augmented image. The method may further allow for manipulation of theaugmented image. The method may be carried out on a device configured toaugment the first image with image data from the second image. Suchdevice may comprise one or more processors. A computer program productcomprising a computer-readable storage medium with instructions may beadapted to carry out the method when executed by a device havingprocessing capabilities.

In short, the method comprises extracting selected image data, pixeldata, from the second image and inserting it into the first image andthereby render the augmented image.

FIG. 1 discloses a first image 100 depicting a first scene. The firstimage 100 may be retrieved from a memory storing the first image 100.The first image 100 may be captured by a mobile device (smartphone, bodyworn camera etc.) and sent to another device for analysis. Any othersuitable means for capturing an image may be used, such as through theuse of a virtual reality, VR, device, or a augmented reality, AR,device, etc. The first image 100 may be provided as a 2D image. In theexample of FIG. 1, the first image 100 depicts the first scene having afloor extending in a X, Z plane, a first wall extending in a Y, Z planeand a second wall extending in an X, Y plane.

A first 3D coordinate space may be determined for the first image 100.The first 3D coordinate space may extend along a X, Y Z plane/direction.The 3D coordinate space may be determined through applying an algorithmto the image. It is to be noted that there are many algorithms that maybe suitable for calculating and determining a 3D coordinate space. Byway of example, the 3D coordinate space may be calculated by applying aPlane detection algorithm, or a RANSAC algorithm, or a Hough algorithm,etc., to the first image 100.

The first image 100 may comprise a plurality of objects, in the exampleof FIG. 1, a three-seat sofa, an armchair, and a coffee table etc.

The first image 100 may be captured using a first field of view.

A virtual scene of the first image may be generated through using adevice comprising one or more processors. The one or more processors maybe configured to execute a computer program product comprising codesections having instructions for a method for how to generate a virtualscene of objects. The device may generate the virtual scene by receivingthe first image and processing said first image. The processing of saidfirst image is done by image analysis and image manipulation. Thegenerated virtual scene may be displayed on the device, or a mobiledevice etc. It is noted that the virtual scene may be displayed on anysuitable means for displaying a virtual scene.

One or more objects in the first image may be identified. The one ormore objects in the first image may be identified using an image searchalgorithm.

In some embodiments, at least one of the one or more identified objectsin the first image may be removed. Alternatively, or additionally, thefirst image 100 may be manipulated as to changing a position of at leastone of the one or more identified objects in the first image.Accordingly, at least one of the one or more identified objects may bemanipulated.

Now turning to FIGS. 2A-2D it will be described in detail how to extractimage data from a second image.

FIG. 2A shows a second scene 200. A second image 300 is captured by animage capturing device 302, as is shown in FIG. 2B. The second image 300may be captured by a mobile device (smartphone, body worn camera etc.)and sent to another device for analysis. The second image 300 may becaptured by any camera device. The second image 300 may be capturedusing AR or VR equipment. The second image 300 depicts a part of thesecond scene 200.

The second image 300 may be captured using a second field of view.

When processing the second image 300, an object 206 is identified. Inthe following example, the identified object 206 will be represented bya chair 206, as is shown in FIG. 2A. It is to be noted that the methodis not limited to identifying furniture as objects in the second image300. By way of example, during construction of a building, theidentified object may be a door or a window.

Identifying an object within the scene may be done by an image searchalgorithm as described above. By the use of an image search algorithm,an object type for the identified object may be determined.

In some embodiments, the identifying of an object 206 in the secondimage 300 may be done by scanning a QR code on the object to beidentified. As such, the object to be identify comprises a QR code. Datapertaining to the object type, an object number may be comprised in theQR code. In other words, an object identifier may be comprised in the QRcode.

The identifying of an object in the second image may be done by readinga beacon signal transmitted by the object to be identified in the secondscene 200. As such, the beacon signal may comprise data pertaining tothe object closest to the image capturing device being the object to beidentified. By way of example, the beacon signal may determine whichobject in the image is closest to the camera device, and thereby saidobject may be the chosen object to be identified. The beacon signal maycomprise data identifying the object and such data may thus betransmitted to the database to receive the corresponding 3D model fromthe database. The beacon technology may use Bluetooth or low energyBluetooth to send the device a beacon signal relating to the identifiedobject.

Any suitable wireless information sharing protocol, such as for examplewi-fi, may be used to transmit the beacon signal.

In another example ultra-wide band technology may be used to identifyobjects, e.g. in conjunction with the capturing the second 300, or thirdimage of the second scene 200. Moreover, ultra-wideband technology mayimprove the spatial awareness of objects in the scene. Theultra-wideband technology may determine a precise location of the objectto be identified in a low-complexity manner. Ultra-wideband technologymay be implemented into the camera capturing device.

Beacon technology may facilitate the identifying of an object in thesecond image, by the placement of beacons in the second scene 200.

In some embodiments, the identifying of an object in the second imagemay be done by requesting an input from a user. It is to be noted that auser input may be requested for other purposes as well and is notlimited to the identification of the object in the second image.Accordingly, a user input may be requested. Consequently, a user inputmay be received. The user input may be requested and received at thedevice capturing the second image, or at another device.

When identifying the object in the second image, an object distance andan object angel may be determined relative to the second field of view.

A second 3D coordinate space may be determined for the second image 300.By determining the second 3D coordinate space, an object coordinate maybe determined for the identified object 206 in said second 3D coordinatespace. The second 3D coordinate space may be determined as describedabove for the first 3D coordinate space.

As is shown in FIG. 2C, a 3D model 304 corresponding to the identifiedobject 206 of the second image 300 is received. The 3D model 304 isreceived from a database comprising a plurality of 3D models. Thereceived 3D model 304 is corresponding to the identified object 206 inthe second image 300.

The 3D model 304 is a 3D model of the chair 206 that has been identifiedin the second image 300. The received 3D model may be based on thedetermined object type of the identified object 206. By sending theobject type to the database, the processing type for retrieving thecorresponding 3D model 304 may be reduced. The object identifier may besent to the database in order to retrieve a corresponding 3D model in anefficient manner. Data pertaining to the received input from the usermay be sent to the database. In other words, data pertaining to theidentified object 206 may be sent to the database.

For the 3D model 304, a first value for a scale parameter may bedefined. For the 3D model 304, a first value for a translation parametermay be defined. For the 3D model 304, a first value for a rotationparameter may be defined. Each one of the first scale parameter, thefirst translation parameter, and the first rotation parameter may bemanipulated.

The 3D model 304 is then aligned to the chair, the identified object206, in the second image 300, such that the 3D model 304 has a contourprojection onto the second image 300 that aligns with the outline of thechair 206. In aligning the 3D model 304 to the identified object 206, asecond value for a scale parameter may be determined for the identifiedobject 206. A second value for a translation parameter may be determinedfor the identified object 206. A second value for a rotation parametermay be determined for the identified object 206.

During the alignment of the 3D model 304, one or more of the first scaleparameter, the first translation parameter, and the first rotationparameter may be manipulated such that the first scale parametercorresponds to the second scale parameter, the first translationparameter corresponds to the second translation parameter and the firstrotation parameter corresponds to the second rotation parameter. Inother words, the 3D model may be manipulated and aligned to the second3D coordinate space of the second image.

Thereafter pixel data 208 of the 3D model's contour projection onto thesecond image 300 is extracted. In other words, pixel data 208 of thechair 206 is extracted from the second image 300.

By aligning the 3D model 304 to the identified object 206, only thepixel data 208 of the identified object 206 is extracted, and thesurrounding of the object is not part of the extracted pixel data 208.As such, a method may be provided that facilitates pixel data extractionfrom an image. This extracted pixel data 208 can then be inserted intothe first image 100 to render the desired augmented image 400.

The extracted pixel data 208 from the example is shown in FIG. 2D.

Now turning to FIG. 3A-3C it will be discussed how the augmented image400 is rendered.

The augmented image 400 is rendered when the extracted pixel data 208 ofthe second image data 300 is inserted into the first image 100, as isshown in FIG. 3A

The pixel data 208 may in some embodiments be inserted at a positionhaving the object distance and the object angle relative to the firstfield of view in the first image 100.

Now turning to FIGS. 3B-3C it is evident that the position of theinserted pixel data in the augmented may be adjusted. This may beachieved by manipulating the first 3D coordinate space of the firstimage. This may be achieved through zooming in or out the first image100. The augmented image 400 may be adjusted through translating thefirst image 100. The position of the inserted pixel data 208 in theaugmented image 400 may be adjusted to correspond to the objectcoordinate in the manipulated 3D coordinate space of the first image100. In another example, the position of the inserted pixel data 208 maybe adjusted by a user manually moving the first image 100 to steer theposition of the inserted pixel data 208. Such an action may be performedon a display. Any suitable display may be used.

The augmented image may be displayed on a display screen. The augmentedimage may be displayed using AR or VR equipment.

The augmented image 400 may be stored in a memory. The first image 100may be stored in the memory. The second image 300 may be stored in thememory. The extracted pixel data 208 may be stored in the memory.

It may be desirous to perform parts of the method iteratively such as toposition the identified object 206 in a desired position in the firstimage 100. This may be done by first removing the inserted pixel data208 from the augmented image 400, and thus allow for insertion ofdifferent pixel data.

Now turning to FIGS. 4A-4B an example of an embodiment wherein theinserted pixel data 208 is removed will be described. FIG. 4A shows athird image of the second scene. The second scene is here depicted froma different field of view compared to previous figures.

The third image may be captured of the second scene using the imagecapturing device. Then the previously identified object 206 isre-identified as the identified object 206. The third image 202 may becaptured form a different distance to the object or have a differentfield of view. Accordingly, a third 3D coordinate space for the thirdimage 202 may be calculated. The 3D model 304 is aligned to theidentified object 206, and pixel data 208 a is extracted from the thirdimage 202 of a contour of the 3D model projection onto the third image202. The extracted pixel data 208 a of the third image 202 is thus notequal to the extracted pixel data 208 from the second image 300. Asecond object coordinate is determined for the identified object 206 inthe third image 202 using the third 3D coordinate space. Then theextracted pixel data 208 a of the third image data is inserted into thefirst image at a position coordinate in the first image corresponding tothe second object coordinate, thereby rendering an augmented image 400.

In the disclosed embodiment shown in FIG. 4B the extracted pixel data208 a depicting the chair 206 is inserted into the first image at aposition coordinate corresponding to the object coordinate of theidentified object in the second image. As such, the realistic view ofthe inserted object into the first image is retained.

As is evident from FIG. 4C, the augmented image 400 may be manipulatedby one or more objects changing positions in the augmented image. InFIG. 4C the sofa, the armchair, and the lamp of the scene has beenremoved from the scene, thereby creating a plurality of empty spaces.Hence, one or more objects of the first image 100 may be identified andmanipulated through removal thereof. The one or more identified objectsof the first image may be manipulated through manipulation of the 3Dcoordinate space first image 100, thereby the identified objects maychange position. One or more objects in the first image may be removedor rearranged to create empty spaces.

The one or more objects of the first image may be manipulated throughmanipulation of the virtual scene depicted in the augmented image. Bythis, the one or more objects may for example be removed from theaugmented image.

Now turning to FIG. 5 there is disclosed a flowchart of the method forrendering an augmented image 400.

The method comprises receiving S02 a first image depicting a firstscene. Using an image capturing device, a second image depicting asecond scene is captured S04. In the second image, an object isidentified S06 as the identified object. A 3D model is received S08 froma database comprising a plurality of 3D models. The received 3D model iscorresponding to the identified object. The 3D model is then aligned S10with the identified object in the second image. Thereafter pixel data isextracted S12 from the second image using a contour of the 3D model'sprojection onto the second image. The extracted pixel data of the secondimage is inserted S14 into the first image, thereby rendering anaugmented image.
